You can use Transact-SQL statements to create user-defined data types. System stored procedures sp_addtype can be used to create user-defined data types.

The main thing is the core features of INDEXEDDB: With cursors and indexes and scopes to really play INDEXEDDB power1. Index: Why is it called INDEXEDDB? Because it gives us the index to query the value we need;2. Cursors: Cursors provide us with the data that we iterate over,3, the scope: and the cu

Playing with application development, I used python to write an encapsulation of the QQ Weibo open platform. This is a file that includes all the interfaces described in this document, which is very simple. Download http://code.google.com/p/python-qweibo. Simple call example:
Import webbrowserimport qweibo o qweibo. init (app_key, app_secret) # You only need to initialize it once. # obtain access tokentoken = qweibo. oauthtoken.

Which accessories will recognize attributes? If there is no module read attribute, it will be worthless. You may put the class that reads the attribute in the same assembly where the attribute resides. However, as mentioned above, you want to put the methods and attributes for reading attributes in different accessories. Public stri
